Steel Cup-Tip Set Screws

Made of alloy steel, these screws are strong enough to hold components without wearing down. The tip has thin edges that dig into surfaces for a secure hold. They often lock gears, pulleys, and other transmission components onto shafts.

Cadmium-Plated Alloy Steel—The plating reduces friction between the screw and your mounting surface to prevent sticking when tightening and loosening. It also creates a barrier against rust.

Military Specification—These screws are manufactured and tested to strict U.S. military standards for material and construction.
